Analysis of wheat harvesting loss rate based on high quality sowing technology
Reducing wheat harvesting losses is not only an effective way to save land and water resources and develop intangible grain fields,but also a practical need for sustainable agricultural development and ensuring food security.Based on high-quality sowing technology,through field investigation and data analysis of the recent machine harvest loss reduction competition in Shandong Province,the influencing factors of wheat harvest loss were explored.The results indicated that moisture content was an important factor affecting the mechanical harvesting loss rate of wheat;the drum form had a certain impact on the wheat harvesting loss rate:the cutting flow+single longitudinal axial flow drum form had the lowest loss rate compared to other drum forms.There was still a certain gap between domestic brands and well-known foreign brands,but the gap has been decreasing year by year.The service life of machinery had a significant impact on the loss rate:after three years of use,the loss rate of machinery will significantly increase.
